What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

CWC SBS Black Ice Quartz Watch

Owners widely praise the CWC SBS Black Ice Quartz Watch for its legible, uncluttered dial, excellent Super-LumiNova lume, and robust build quality, noting its comfortable 12mm thickness and durable PVD coating. The bezel action is described as having zero back play, and the fixed lugs are appreciated for easy strap changes. One owner reported the lume is readable throughout the night, while another flagged a faulty mechanism requiring replacement and poor retailer customer service. The £700 price is considered high by some compared to similar quartz divers, leading to questions about its value. Overall, owners rate the CWC SBS Black Ice Quartz Watch highly for its bombproof, toolish design and practical aesthetics.

Seiko Prospex Sea PADI Special Edition

The Seiko Prospex Sea PADI Special Edition is widely praised for its attractive blue and red PADI colors, rich dial aesthetic, and excellent lume that stands out even in dim environments. Owners highlight its robust build quality and excellent bezel action, noting the wave dial is a favorite. However, the Hardlex crystal and the 4R36 movement's accuracy range of +45 to -35 seconds per day are identified as compromises for the price. Some owners find the diver's extension difficult to open and the bracelet adjustment challenging, though manageable. On balance, owners and reviewers rate the Seiko Prospex Sea PADI Special Edition highly for its build quality and striking dial design at its price point.
